  • Spray method for monolithic refractories
    Patent number: 6592048
    Abstract: A spray method for monolithic refractories, which comprises feeding, with an air stream, a monolithic refractory composition including a rapid setting agent in addition to refractory aggregates, a refractory powder, a binder and a dispersant in a powder state in a transporting pipe so that the composition is transported in a floating state; adding application water on the way of the transporting pipe; continuing the feeding of the air stream, and spraying the wet composition through a spray nozzle. In a case that the monolithic refractory composition does not include the rapid setting agent, the rapid setting agent is added at an upstream side of the top end of the spray nozzle, and then, the wet refractory composition is sprayed through the spray nozzle.
